“In recent weeks, we have become increasingly concerned at the continued leaks regarding sensitive intelligence programs and activities, including specific details of sources and methods. The accelerating pace of such disclosures, the sensitivity of the matters in question, and the harm caused to our national security interests is alarming and unacceptable.

“These disclosures have seriously interfered with ongoing intelligence programs and have put at jeopardy our intelligence capability to act in the future. Each disclosure puts American lives at risk, makes it more difficult to recruit assets, strains the trust of our partners, and threatens imminent and irreparable damage to our national security in the face of urgent and rapidly adapting threats worldwide.

“As leaders of the House and Senate Intelligence Committees, we are jointly committed to act immediately to address this matter. Our Committees each intend to review potential legislation to strengthen authorities and procedures with respect to access to classified information and disclosure of it, as well as to ensure that criminal and administrative measures are taken each time sensitive information is improperly disclosed. We also intend to press for the Executive branch to take tangible and demonstrable steps to detect and deter intelligence leaks, and to fully, fairly, and impartially investigate the disclosures that have already taken place. We plan to move legislation quickly, to include possible action in this year’s intelligence authorization act.

“The problem of leaks of classified information is not new, and efforts in the past to address it have not worked. We believe that significant changes are needed, in legislation, in the culture of the agencies that deal with classified information, in punishing leaks, and in the level of leadership across the government to make clear that these types of disclosures will not stand.”
